The Town of Andover Building Department requires a permit for any window or door replacement that changes the opening size, structural framing, or egress configuration. Like-for-like full-frame replacements in the existing rough opening typically don't need a permit but must meet current egress code. Properties in the Andover Center Historic District and the Phillips Academy area need additional Historical Commission review for visible exterior changes — sash material, profile, muntin pattern, and glazing all come under review. The pre-1978 share of the housing stock falls under federal lead-safe RRP rules, adding $50–$150 per opening for documented containment.

Window-and-door pricing in Andover sits in the top tier of MA suburban pricing — driven by higher-spec product mix, premium installers, and historic-district compliance on a meaningful share of jobs. Standard vinyl full-frame replacements typically run $750–$1,200 per opening installed (rarely the chosen spec); mid-grade composite or wood-clad units run $1,600–$3,200 per opening; premium wood or historic-compatible product runs $2,200–$5,000 per opening. Entry door replacement is typically $2,800–$7,000 installed depending on material and sidelights. Large patio sliders run $4,000–$10,000.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential window & door installation work; ask for the registration number and check it before paying a deposit.
